| Quantifying water balance components is crucial to understanding the basic hydrology and hydrochemistry. An importance of water balance has been suggested in order to grasp actual condition of water resources and environmental changes including climatic changes. The present paper proposes an evaluation method of the water balance components based on vegetation monitoring from remote sensing data. In this study, evapotranspiration model adopts a directmethod by using NDVI (Normalized Difference Vegetation Index) calculated from NOAA/AVHRR data and the detailed description of water balance by using the evapotranspiration in all over the Korean Peninsula. Areal distribution data sets of evapotranspiration in all over the Korean Peninsula. Areal distribution data sets of evapotranspiration, runoff ratio, water surplus and deficit are produced using NDVI and simplified water balance model. This method enables to discuss the hydrological problems for North Korea where enough meteorological and hydrological data are unavailable. |
